Expiration: 500 AM MST SAT AUG 30 2008

...SIGNIFICANT SHOWERS AND THUNDERSTORMS EXPECTED DURING THE LABOR
DAY WEEKEND OVER SOUTHEAST CALIFORNIA...SOUTHWEST AND SOUTH-CENTRAL
ARIZONA...

ACTIVE WEATHER IS EXPECTED TO DEVELOP THIS HOLIDAY WEEKEND...AS AN
APPROACHING PACIFIC LOW PRESSURE SYSTEM DRAWS MOISTURE NORTHWARD INTO
THE AREA...AND THEN PRODUCES INCREASING SHOWER AND THUNDERSTORM
ACTIVITY ACROSS MUCH OF SOUTHERN ARIZONA AND SOUTHEASTERN CALIFORNIA.

SCATTERED SHOWERS AND THUNDERSTORMS ARE FORECAST TO DEVELOP OVER
SOUTHEAST CALIFORNIA...SOUTHEAST AND SOUTH-CENTRAL ARIZONA ON
SATURDAY AFTERNOON AND EVENING. LOCALLY HEAVY RAINFALL AND STRONG
GUSTY AND DAMAGING WINDS ARE ALL POSSIBLE WITH THE STRONGER
THUNDERSTORMS. AS THE LOW PRESSURE SYSTEM APPROACHES FROM THE
NORTHWEST ON SUNDAY...THE FOCUS FOR STRONG AND POSSIBLY SEVERE
THUNDERSTORMS WILL SHIFT EASTWARD INTO SOUTH-CENTRAL ARIZONA.

SOME OF THE MOST SIGNIFICANT WEATHER WILL LIKELY OCCUR OVER SOUTH-
CENTRAL ARIZONA...INCLUDING THE GREATER PHOENIX METROPOLITAN
AREA...ON SUNDAY AFTERNOON AND EVENING. THE STRONGER THUNDERSTORMS
HAVE THE POTENTIAL TO PRODUCE VERY HEAVY RAINFALL WITH FLASH
FLOODING...STRONG WINDS IN EXCESS OF 60 MPH...MODERATE HAIL AND
DEADLY CLOUD TO GROUND LIGHTNING. IN ADDITION TO THE SCATTERED
THUNDERSTORMS THIS WEEKEND...SOMEWHAT COOLER CONDITIONS ARE EXPECTED
AS HIGHS BOTH DAYS ARE FORECAST TO DROP BELOW SEASONAL NORMALS.

SHOWERS AND THUNDERSTORMS WILL DECREASE SUBSTANTIALLY FROM THE WEST
ON LABOR DAY...AS DRIER AIR SPREADS IN FROM THE WEST. THERE WILL
STILL BE A CHANCE FOR AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS...MAINLY OVER THE HIGHER TERRAIN EAST OF PHOENIX.
